WASHINGTON — The U.S. dollar index surged to 105.3 today, its strongest level since November, after North Korea rejected President Trump's proposal to resume high-level diplomatic talks with Kim Jong Un. The rejection triggered an immediate flight to safety, with investors rotating into Treasuries and the dollar at the expense of equities.

Major stock indices fell sharply: the Dow Jones dropped 1.3 percent, the Nasdaq 1.0 percent, and the S&P 500 0.9 percent.

Trump had signaled openness to a third summit with Kim. North Korean officials responded that talks would be futile without substantial U.S. policy changes, particularly on sanctions relief—a position consistent with years of diplomatic deadlock.

The fixed-income market transmitted the shift immediately. Long-dated Treasuries rallied as investors de-risked, driving yields lower and compressing the curve as the belly outperformed. The 10-year Treasury yield, a barometer of institutional duration appetite, fell as safe-haven inflows accelerated. For bond portfolio managers, the geopolitical shock forces a sharp reassessment of interest rate exposure and the timing of any curve steepening trades.

The dollar's strength reflects its role as the crisis hedge in a risk-off environment. Capital is redirecting away from growth assets and emerging markets, consolidating in dollar-denominated government debt. This reallocation will persist as long as the diplomatic impasse holds.
